The summit is near freezing even in August. This is the honest list — what you actually need, what you can rent in Tokyo, and realistic prices.
Why this matters

These are non-negotiable. Skipping any is genuinely risky.
Volcanic gravel is merciless on regular sneakers. Ankle support prevents injuries on the descent.
